I had what felt like
high blood pressure or a sped up heart rate. I thought I also had low
blood sugar because of shivering/shaking, fatigue, and dizzyness.
I had consumed about 3000 IU of vitamin E that night, and I thought maybe it was a Vit. E overdose, resulting in renal failure. Since then, I've had a blood test that shows my kidneys are perfectly fine.
The doctor said judging by the symptoms, it's probably epididymitis.
